> The industrial revolution rendered a lot of traditional blacksmith work — making hammers, nails, axes, shovels and more — obsolete. But blacksmiths like Mr. Kaviar, 69, have found success creating so-called “functional art.” Mr. Kaviar, for instance, is regionally known for making handrails forged with leaves and birds that have a rough-hewed, borderline macabre design evocative of the work of sculptors like Louise Bourgeois.
You explicitly mention "horsehoes and nails", but I don't think that's a reasonable thing to expect: Especially for nails, I don't think many people would spend money on something that isn't really going to be visible. (I don't know enough about the farrier trade to say the same for horseshoes.) By contrast, a handrail is something that can be very visible.
